What does this mean in the overall picture of efficiency? I'm an EE but haven't really played with mining just yet.
Even really good AC to DC converters will lose you 8-10% and state of the art is probably like 3-5% under perfect conditions. I wonder if commercial miners will get on this tip and invest in DC microgrids
Out of the box the jPro advertises 30 j/Th, but I see folks using aftermarket firmware getting 26, maybe even a bit less, with a jPro. So sub 20 j/Th is a significant improvement.
Building out a microgrid is pretty capital intensive, so I imagine miners will continue trying to find places where cheap power is stranded that doesn't require as much capex to get off the ground. Although adding this to existing solar farms could be a great way to use electricity when there's excess. I'd guess it's already being done.
